grain structure (finer for forged products), tensile strength (generally superior for forged products) and fatigue resistance.浇铸和锻造工艺产生的产品在表面孔隙度（锻造产品通常优于毛细成形技术产品）、晶粒结构（锻造产品更细）、抗拉强度
If the precipitation is prevented by some devices, the tensile strength of stainless steels would be decreased continuously with rise of temperature, as pure metals do. This assumption was confirmed by a tensile test on sharp-notched specimen. It may be reasonable to conclude that the strength ...
Experiments of tensile mechanical properties of steel 0Cr18Ni9 are done on the MTS 810 tensile testing machine, and the temperature range is from 20°C to 1200°C. The stress vs. strain curves are obtained. Results show that the elastic modulus, yield stress and tensile strength decrease with ...
Xin-Xin Wang, in Behavior and Design of High-Strength Constructional Steel, 2021 5.1 Introduction High-strength steel (HSS) is quite vulnerable to the fire and high temperature due to the high thermal conductivity and low specific heat. To ensure the safety of the HSS structures in an entire...
In all the test presented, the material’s yield strength is considered to be constant. However, the solver easily allows this property to be temperature dependent using a piecewise linear interpolated table, which consequently makes it implicitly dependent on the load history. The second stage of...
heat process was investigated by means of metallography and electron microscopy in Ultra-high Strength Steel with tensile strength 1000Mpa. The results show that microstructure variation in the steel with tempering temperature increasing is as follows:tempered martensiteâmain tempered sorbite ...
Parts made of a heat-treated alloy steel having a minimum tensile strength of 700 N/mmand a notch toughness of at least 55 joules, wherein the alloy steel is a Mn/Cr/Nb alloy steel of lower alloy content than has hitherto been used to provide the desired strength/toughness properties.收...
In present work, the tensile tests of SS304 stainless steel sheet were performed at different orientations (i.e., 0°/RD, 45°/RD and 90°/RD). The mechanical properties of the material (Young’s modulus, ultimate strength, yield stress and hardening curve etc.) were computed with the ...
This aids the activation of the nano-twinning mechanism during the tensile deformation of SLM-built SS316L at room temperature, which simultaneously increases the strength and ductility. This work proposes a promising solution to improve the mechanical performance of metal AM components while using ...
