Alternative Approach for the Intercritical Annealing of (Cr, Mo, V)-Alloyed TRIP-Assisted Steel before Austempering

open access: yesMetals, 2022
TRIP-assisted C-Si-Mn steels are usually subjected to austempering with a preliminary intercritical annealing that is targeted at the multi-phase structure with 40–60 vol.% of proeutectoid ferrite.

Effect of Sample Geometry on Strain Uniformity and Double Hit Compression Tests for Softening Kinetics Determination

open access: yessteel research international, Volume 93, Issue 12, December 2022., 2022
The strain non‐uniformity affects the localized softening fraction, eventually affecting the calculated softening fraction from the flow stress of double hit tests. In this study, uniaxial compression tests, standard plane strain compression tests (PSCT), and modified PSCT samples are used to see the effect of different geometries on strain uniformity ...

Contrasting Effects of Laser Shock Peening on Austenite and Martensite Phase Distribution and Hardness of Nitinol

open access: yesCrystals, 2022
Laser shock peening of cold rolled Nitinol was carried out at high power density (7 and 9 GW/cm2) and high overlap ratio (90%). Tensile surface residual stresses were generated in the peened material.

Bonding Experiments at Elevated Temperatures: The Effect of the Sample Storage Time on the Bond Strength of Metals

open access: yessteel research international, Volume 94, Issue 1, January 2023., 2023
For the production of metallic composites, the achievable bonding strength plays a major role in this process. The determination of the bonding strength is quite challenging. One reason for this is the oxidation behavior. Therefore, the effect of storage time on the determination of several metallic bonds is investigated for different bonding ...

Ball Milling Effect on Corrosion and Biocompatibility Behavior of FeMnC Alloys Produced by Powder Metallurgy in Simulated Body Fluids Environment

open access: yesMetals, 2021
Carbon-containing Fe-Mn alloys have been developed for the materials for stent application. The alloys fabricated by the powder metallurgy route retain a significant amount of porosity and require a longer sintering time.

Insight into the Induction Hardening Behavior of a New 0.40% C Microalloyed Steel: Effects of Initial Microstructure and Thermal Cycles [PDF]

open access: yes, 2018
The induction hardening behavior of a new, hot-rolled 0.4 wt.% carbon steel with the two different starting microstructures of upper and lower bainite has been simulated using a Gleeble 3800. The effect of heating rate in the range 1 - 500 {\deg}C/s on austenite grain size distribution has been rationalized.

Simulation of the thermally induced austenitic phase transition in NiTi nanoparticles [PDF]

open access: yesEuropean Physical Journal B 84, 109-113 (2011), 2011
The reverse martensitic ("austenitic") transformation upon heating of equiatomic nickel-titanium nanoparticles with diameters between 4 and 17 nm is analyzed by means of molecular-dynamics simulations with a semi-empirical model potential. After constructing an appropriate order parameter to distinguish locally between the monoclinic B19' at low and ...

A theoretical review of the operation of vibratory stress relief with particular reference to the stabilization of large-scale fabrications [PDF]

open access: yes, 2011
Vibratory stress relief (VSR) is widely used on large welded fabrications to stabilize the structures so that they do not distort during further machining or during operational duty.
