Effect of Heat Treatment on Mechanical Properties

Engineering materials, mostly steel, are heat treated under controlled sequence of heating and cooling to alter their physical and mechanical properties to meet desired engineering applications. In this study, the effect of heat treatment (annealing, normalising, hardening, and tempering) on the microstructure and some selected mechanical properties of NST 37-2 steel were studied. Investigation on microstructure and mechanical properties Microstructure characterization and mechanical properties testing. The extruded Al plates were sectioned and prepared for microstructure observation, hardness, and tensile tests. The width, length, and thickness of the extruded plate were defined as TD, ED, and ND directions, respectively.


The microstructure and mechanical properties of extruded Ti-45A1-X(Nb,B,C) (at.%) were evaluated in both an as-extruded condition and after a lamellar heat treatment. Tensile behavior of both as-extruded and lamellar heat TiAl ingots were extruded in two steps at a nominal billet preheat Microstructure and Mechanical Properties of Ultra-High Ultra-high strength steel plates fabricated by a modified thermo-mechanical control process showed lower yield ratio of under 0.75 and higher uniform elongation of 5% as a minimum, as compared to commercial API X100 and X120 grade pipeline steels, without much sacrifice of Charpy impact properties because of an appropriate formation of soft Microstructure, Mechanical Properties, and Corrosion Apr 07, 2018 · 3.1. Mechanical Properties and Microstructure. The AlZn6Mg0.8Zr alloy subjected to LTTT reveals a yield point from approximately 256 MPa to about 300 MPa and tensile strength from approximately 321 MPa to 347 MPa, depending on the degree of cold deformation after solution heat treatment in a range from 10 to 30% (Figure 3 a).

Non-destructive determination of microstructural

Sep 05, 2019 · In this paper, a combination of non-destructive magnetic technique and artificial neural networks is introduced, firstly, to ensure that the heat treatment process applied to a given API X65 steel sample results in desired microstructure and mechanical properties and secondly, to determine thickness variation which may occurs as a result of REPOSITORIO INSTITUCIONAL DA UFOP:Microstructure and Microstructure and mechanical properties of two API steels for iron ore pipelines.
