Chemical heterogeneity enhances hydrogen resistance in

Jul 08, 2021 · Our high-strength steel (strength level ~1GPa) contains submicrometre-sized domains of ferrite () and austenite (, Fig. 1b) and shows the transformation-induced plasticity (TRIP) effect, Deformation mechanisms of 304L stainless steel with Jan 10, 2019 · Deformation behavior of 304L stainless steel with heterogeneous lamella structure mainly contains three stages:yield drop stage (~0.22%), involving accumulation of stacking faults/geometrically necessary dislocations and initiation of strain-induced martensitic transformation (SIMT); high-speed work-hardening stage (~215%), related to dislocation slipping and SIMT; steady work-hardening stage

High Strength and Ductility of Additively Manufactured

Apr 11, 2018 · The as-built samples have higher hardness, strength, and ductility relative to the as-cast 316L stainless steel. Both the horizontal (HB) and vertical (VB) as-built samples show a similar yield strength. However, the HB samples show a higher tensile strength High Temperature Deformation Characteristics of an Alumina Eventually, the optimum high temperature deformation parameters can be determined as 10501120 0.010.1 s1 and 11201150 °C/100.5101.5 s1 for this AFA alloy. This paper focuses on hot High strain rate deformation microstructures of stainless Mar 01, 2008 · Cold spraying is a new coating technique in which dense, tightly bonded coatings form only due to the high kinetic energy of impinging particles of the spray powder. These particles are still in the solid state during impact. Explosive powder compaction is a technique where powder is consolidated by a shock wave. In the shock front the powder is deformed under high strain rates, which under

Hot Deformation and Dynamic Recrystallization of 17-4

strength, have made it very attractive to designers and engi-neers.7) Hot deformation processing such as forging for this steel is conducted in the temperature range of stability of austenite phase.8) Due to the low stacking fault energy of austenite in the 17-4 PH stainless steel, the major restoration Microstructural refinement and deformation twinning during Mar 03, 2011 · The present work focuses on the severe plastic deformation and deformation twinning of 316L austenitic stainless steel deformed at high temperatures (700 and 800 °C) using equal channel angular extrusion (ECAE). Recrystallization following hot-working of a high-strength The recovery and recrystallization behavior of two commercial quality steels, a Cb(Nb) strengthened high-strength low-alloy (HSLA) steel and a 304 stainless steel, was studied following hot-working. Specimens were deformed in tension at a constant head velocity of 2 in.Js to reductions-in-area of 30 to 50 pct at temperatures in the austenite range from 1600° to 1900°F.

Tensile strength stainless steel Gutekunst Formfedern

Jul 30, 2021 · This tensile strength value describes the plastic deformation limit im Stress-strain diagram of the material. Calculation of tensile strength. The tensile strength becomes during a tensile test from the maximum tensile force achieved based on the cross-section calculated from a standardized tensile test. Tensile strength of stainless steel High-Temperature Deformation Characteristics and Mar 23, 2021 · The high-temperature deformation characteristics of an ultrahigh strength steel is studied by hot compression tests under the deformation temperatures of 9201160 °C and strain rates of 0.0110 s 1. By employing the metalloscope and transmission electron microscope, the influences of deformation parameters (deformation temperature and strain rate) upon microstructure evolution are
