The transformation between the face centered cubic austenitic and hexagonal closepacked martensitic phases during highpressure torsion processing was observed in a FeMnCAl twinninginduced plasticity steel.This phase transformation was not found in the same material processed by unidirectional compressive and tensile deformation.Cited by 1Publish Year 2015Author R.Kreethi,P.Sampark,Goutam Kumar Majhi,Krishna DuttaMartensitic Transformation During Compressive Deformation ·The martensitic transformation was the most difficult in the DRX grains because of the effect of small grain size.The tendency of transformation was decreased after compression at 1000 °C.Hot compression tests of a new high-Mn austenitic steel were carried out at deformation temperatures of 700,800,900,and 1000 °C under strain rate of 0 Cited by 4Publish Year 2018Author M.Eskandari,M.A.Mohtadi-Bonab,A.Zarei-Hanzaki,S.M.FatemiHigh Strain Rate Compression of Martensitic NiTi Shape Sep 22,2015·The compressive response of martensitic NiTi shape memory alloys (SMAs) under high strain rate (1200 s1) was investigated on a modified Kolsky (Split Hopkinson) compression bar.The single-loading momentum trapping system ensures precise deformation control (1.4,1.8,3.0,4.8,and 9.6 % strain) and single loading during dynamic compression.

The two specimens exhibited identical deformation behaviour,both during initial loading,which was a stress-induced martensitic transformation process,and during subsequent cycling,which was a marten-site reorientation process.The cyclic deformation was terminated at g17% at t = 0 MPa for both samples.Figure 2(b) shows the shape recovery ofHigh strain rate deformation of martensitic NiTi shape In the present work,the mechanical behavior of a martensitic NiTi SMA under very high state rate (3 {times} 10{sup 3} s{sup {minus}1}) compression is obtained and is primarily compared to its low rate (3 {times} 10{sup {minus}4} s{sup {minus}1}) deformation behavior.In Situ TEM Observation on Martensitic Transformation Further study is necessary.Literature on martensitic transformation mechanism studied by in situ TEM has rarely been published.In this study,the martensitic transformation during tensile deformation in SUS304 stainless steel was observed directly by the in situ TEM technique.

Feb 01,2011·The strengthening behavior during deformation in the Cu 46.5 Zr 48.5 Al 5 alloy is ascribed to an austenitetomartensite phase transformation whereas the hardening and plasticity in Cu 50 Zr 50 were governed by the large amounts of twin boundaries and a deformationinduced phase transformation within the alreadyexisting martensitic phase.
