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: Metal additive manufacturing (AM) is a process of making 3D metal parts layer by layer through the interaction between a heating source and feeding material from a digital design model. Post-AM heat treatment is needed to modify microstructure and alleviate residual stresses for achieving comparable or superior properties to conventionally manufactured counterparts. This review discusses the influence of heat treatment on microstructure, mechanical properties, and corrosion behavior of major categories of AM metals, highlighting the significant differences between AM metals and their conventionally manufactured counterparts.

Summary: This study investigated the influence of heat treatment on the microstructure and high-temperature mechanical properties of Inconel 740H superalloy. Various heat treatments were conducted, and the samples exhibited similar gamma-matrix with spherical gamma' particles. The fractions of carbides at the grain boundaries varied, and the samples showed similar microhardness and tensile properties. Thermal exposure and creep tests revealed differences in the growth of gamma', microhardness, and creep life of the samples. The presence of MC carbides in the sample helped accommodate stress exerted on grain boundaries. (c) 2023 Elsevier B.V. All rights reserved.

Summary: Cold sintering combined with annealing processes was used to synthesize high-quality Ca2.7Bi0.3Co3.92O9+delta ceramics, and the effects on thermoelectric performance were studied. By optimizing heat-treatment, the formation of secondary phases, texture development and porosity were controlled, resulting in enhanced electrical conductivity and reduced thermal conductivity.

Summary: The study shows that deep cryogenic treatment can enhance carbide precipitation and promote more homogeneous distribution in steels. The effectiveness of DCT is influenced by the chemical composition of the steel and the predefined matrix microstructure. Incorporating DCT with higher austenitizing and lower tempering temperatures in heat treatment process is the most suitable for improving steels’ properties with DCT.

Summary: The study fabricated 2.6vol% TiBw/Ti6Al4V composites with a network architecture through hot press sintering at 1100 degrees C for 1 hour, establishing quantitative relationships between phases and heat treatment temperatures. It was found that the volume fraction phases changed linearly with solution and aging temperatures, resulting in equiaxed microstructure composites with different high temperature tensile strengths and elongations. Fractured morphology analysis indicated the strengthening effect of TiBw at lower temperatures, but debonding at 700 degrees C significantly reduced this effect.

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 effect of different heat treatment procedures on the tensile, hardness, and fatigue properties of additively manufactured AlSi10Mg. The results show that the as-built samples have the highest yield and tensile strength but limited ductility, while increasing the peak heat treatment temperature improves ductility at the cost of strength. The microhardness decreases with increasing heat treatment temperature. The microstructural transformation induced by heat treatment significantly influences the mechanical properties and fatigue resistance of the SLM AlSi10Mg alloy, mainly due to the disintegration of the Al-Si cellular network and the formation of discrete Si particles at high temperatures.

Summary: A homogeneous CuCr50 alloy ingot with a nonequilibrium solidification structure was prepared by thermite reduction-electromagnetic casting. The effects of heat treatment on the microstructure of the alloy were investigated, and the conductivity, macrohardness, and tensile strength were measured. The optimal heat treatment conditions were determined to be 975℃ for 1 hour for solution treatment and 500℃ for 2 hours for aging treatment. Under these conditions, the CuCr50 alloy exhibited the best hardness, conductivity, and tensile strength.
