Summary: The hot cracking susceptibility of Haynes 282 alloy with varying amounts of C, Mn, Si, B, and Zr was investigated. The study found that the synergistic role of C and B affects the susceptibility to solidification and heat-affected zone liquation cracking. High amounts of C and B promote the formation of eutectic constituents during solidification and facilitate crack healing. Thermodynamic simulations showed that C and B combine with MC carbides and M3B2 borides during solidification. Analysis revealed that C and B are present in both solid solution and precipitates. In the heat-affected zone, these phases promote liquation cracking, and the extent of cracking correlates with the amount of carbides and borides. Lower amounts of C and B were found to reduce liquation cracking. A high-temperature homogenization heat treatment exacerbated cracking by dissolving borides and releasing B to the grain boundaries.

Summary: Friction stir welding of precipitation strengthened nickel-based superalloy exhibited superior mechanical properties and microstructural characteristics compared to fusion welding, showing higher strength, fine-grained microstructure, absence of defects like voids and cracks, and no elemental segregation. This alternative non-melting welding technique is considered efficient for joining nickel alloys in extreme operating conditions like A-USC steam plants.

Summary: Understanding the microstructural behaviour of materials during thermomechanical processing is crucial for achieving optimal mechanical properties. We investigated the dynamic recrystallization (DRX) behaviour of Ni-base superalloy Haynes 282 during hot compression and observed the formation of small DRX grains before the peak strain. The DRX process accelerated significantly above a certain strain, and the material was fully recrystallized at a higher strain. Contrary to common assumptions, many DRX grains contained dislocation substructures, even at small strains.

Summary: In industrial forging, dynamic recrystallization (DRX) can further progress under static conditions, known as meta-dynamic recrystallization (mDRX), which greatly affects grain size and properties. This study investigates the mDRX evolution in Ni-based superalloy Haynes 282 during post-deformation hold times. The results show that mDRX dominates the microstructure evolution during hold time, and the kinetics of mDRX is influenced by the prior strain.

Summary: This study investigates the microstructure, hardness, impact toughness, and tensile properties of Haynes (R) 282 alloy after accelerated ageing. The results show that ageing promotes grain growth and precipitation of various phases and carbides, leading to a decrease in ductility and impact strength. The alloy shows serrated flow in high-temperature tensile tests, and the type of serrations depends on the ageing treatment. Fractographic examination reveals a transition from ductile fracture to brittle intergranular fracture with increasing ageing duration.

Summary: Current numerical prediction methods for determining geometric distortion in manufacturing are limited. This study proposes an innovative method to identify the critical factors for distortion and develops a finite element based framework to validate the hypothesis. The framework is applied to an experimental non-prismatic industrial part and supports the hypothesis that quenching is the most significant contributor to distortion in thin-walled parts made from Haynes 282 alloy. The framework/model provides valuable insights into the contributions of thermal gradients and material state towards part distortion, and overcomes the limitations of current numerical prediction methods.

Summary: In this research, microstructure-based modeling is used to predict the fatigue crack nucleation life of a nickel-based alloy, Haynes 282, under different strain amplitudes. A three-dimensional polycrystalline aggregate is constructed as the material representative volume element (RVE) using Voronoi tessellation with grain orientations assigned by random functions. The model successfully predicts the fatigue crack nucleation life of Haynes 282 alloy and estimates the scattering of the fatigue life. The effect of grain orientation on fatigue crack nucleation is also discussed.

Summary: This study investigates the evolution of microstructure and hardness of Haynes 282 alloy using arc heat treatment, followed by thermodynamic modeling of gamma' precipitation. Results show that different arc heat treatment times have an impact on the alloy's microstructure and hardness, with the temperature range and hardness of the gamma' precipitation zone increasing with time. The gamma' precipitation model demonstrates good agreement with experimental results.

Summary: The effect of ageing time and temperature on the deformation mechanism and tensile properties of a gamma/gamma' Ni-based superalloy, HAYNES 282, was investigated. Different microstructural features were achieved by varying the duration and temperature of ageing, leading to significant variations in strengthening. The size of the gamma' precipitates and the presence of micro carbides were found to play crucial roles in determining the strength of the alloy.

Summary: This article analyzes the influence of various process parameters on the geometrical characteristics and microstructural features of laser-direct energy deposited single-track Alloy 718 specimens, and investigates the effect of heat treatments on the deposits. The research aims to reduce the amount of secondary Nb-rich precipitates either during the process or by subsequent heat treatments. The results indicate that processing at high laser power conditions is effective in minimizing segregation, and heat treatments lead to dissolution of Nb-rich phases and delta phase precipitation in specific regions of the specimens.

Summary: Laser powder bed fusion (PBF-LB) is an additive manufacturing process with advantages of near net-shaping and reduced material wastage. This study optimized the process parameters and investigated their influence on porosity, microstructure, and hardness of JBK-75 austenitic stainless steel. The optimal parameters were found to be 132 W laser power, 750 mm/s scan speed, layer thickness 30μm, and 0.12 mm hatch distance. The effects of hot isostatic pressing (HIP) on tensile properties were also studied, with a slight decrease in strength observed after HIP treatment.
