Summary: This study evaluates the effects of thermo-mechanical processing on the strength-ductility combination of low-density steel. The results show that the alloy composition, cold rolling, and heat treatment temperature influence the concurrent precipitation of particles and recrystallization, as well as the mechanical properties. The Mn/Ni ratio plays a crucial role in controlling the precipitation and recrystallization, leading to variations in the mechanical properties. The findings highlight the importance of precise control of processing parameters in enhancing the strength-ductility combination of low-density steel.

Summary: The study investigated the tensile properties and microstructure of aluminized AISI 321 stainless steel prepared by pack cementation with subsequent annealing. The results showed that the coatings were mainly composed of Al2O3 layer, Fe-Al compound intermediate layer, and Fe(Al,Cr) solid solution diffusion layer. Annealing increased coating thickness, reduced NiAl precipitate size, and affected the strength and plasticity of the stainless steel.

Summary: The purpose of this study is to investigate two new heat treatment processes and their effects on the mechanical properties of TC10 titanium alloy. The results showed that by changing the beta annealing temperature, the microstructure type of the alloy changes from equiaxed to lamellar, leading to an increase in strength and a decrease in plasticity. The fracture morphology also differs depending on the microstructure, with equiaxed structure showing ductile fracture characteristics and lamellar microstructure showing brittle fracture characteristics. These findings suggest that different types of microstructure and mechanical properties can be obtained by setting a suitable beta annealing temperature, thus expanding the application field of TC10 titanium alloy.

Summary: This study investigates the influence of heat treatment on the microstructure and mechanical properties of Ti-47.5Al-3Nb-1.5Cr samples. The results demonstrate that heat treatment at 1623 K leads to refined interlamellar spacing and uniform elemental diffusion in the samples. Furthermore, holding the samples at 1623 K for 1 hour and air-cooling results in the best improvement in mechanical properties, with significant increases in tensile strength and elongation at break.

Summary: The processing conditions to achieve the desired tensile strength and minimum retained austenite fraction in hot-rolled 3-4%Mn medium Mn steels were investigated using quenching and partitioning (QP) and austenite reverse transformation (ART) treatments. The results showed that both processes can achieve relatively high fractions of austenite, with comparable results to those predicted by thermodynamic equilibrium.

Summary: The study investigated the influence of heat treatment on microstructural homogeneity and tensile properties of TA15 powder ingots. The optimal heat treatment route of solution and aging treatment significantly improved the microstructure homogeneity and increased tensile strength by precipitating secondary alpha s phase within the beta matrix. Additionally, detailed discussions on fracture mechanisms for different microstructures were also conducted.

Summary: This paper investigates the microstructure and tensile properties of AISI M50 steel under multiple quenching treatments. Increasing the number of quenching from 1 to 3 results in a larger grain size and a transformation of martensite morphology. The volume fraction of retained austenite decreases as the quenching number increases, reaching a stable level under triple quenching. The ultimate tensile strength peaks under double quenching and decreases with increasing quenching time. Double quenching produces a 2.8 GPa AISI M50 steel with an elongation rate of 2.4%, showing promise in the strengthening of high carbon steels.

Summary: The low-temperature impact toughness of a low-carbon bainitic steel joint for high-speed trains was evaluated using laser-arc hybrid welding. The microstructure of each micro-zone in the welded joint was mainly bainite, but with different morphology and size. The impact toughness varied in each micro-zone due to the content of high-angle grain boundaries and the size of martensite-austenite (M-A) constituent.

Summary: Sandwich-type Al1060/Al6061-0.5SiC/Al1060 laminates were fabricated by hot roll bonding and then subjected to heat treatment. The heat treatment effectively improved the tensile properties of the laminates, with the inhomogeneity of microstructure throughout the thickness of the Al1060 layer being present in the as-rolled laminates.
