Transformation characteristics of γ→ε-M and ε-M→α'-M in high manganese steel under high speed compression

Cailiao gongcheng, 2021
The volume fractions of γ (austenite), ε-M (hcp martensite) and α'-M (bcc martensite) in static and high speed compressed high manganese transformation induced plasticity (TRIP) steel were calculated by the XRD technique to investigate the effect of ...

Tuning macro-twinned domain sizes and the b-variants content of the adaptive 14-modulated martensite in epitaxial Ni-Mn-Ga films by co-sputtering [PDF]

Acta Materiala 59 (2011) 75-81, 2010
In order to obtain modulated-martensite in our epitaxial Ni-Mn-Ga films, we have tuned the composition by using a co-sputtering process. Here we present how the composition affects the variant distribution of the 14-modulated martensite at room temperature.

Advancements in left ventricular assist devices to prevent pump thrombosis and blood coagulopathy

Journal of Anatomy, Volume 242, Issue 1, Page 29-49, January 2023., 2023
Left ventricular assist device (LVAD)‐related blood coagulopathy: Pump thrombosis is one of the most severe adverse events caused by LVADs. The contact of blood with artificial materials of LVAD pumps and cannulas triggers the coagulation cascade. Abstract Mechanical circulatory support (MCS) devices, such as left ventricular assist devices (LVADs) are

Deformation behavior of duplex austenite and ε-martensite high-Mn steel

Science and Technology of Advanced Materials, 2013
Deformation and work hardening behavior of Fe–17Mn–0.02C steel containing ε-martensite within the austenite matrix have been investigated by means of in situ microstructural observations and x-ray diffraction analysis. During deformation, the steel shows

Discontinuous lath martensite transformation and its relationship with annealing twin of parent austenite and cooling rate in low carbon RAFM steel

Materials & Design, 2021
Lath martensite transformation in low carbon steel relates to the discontinuity of the transformation rate, which exhibits a series of martensite transformation rate maxima (peaks), especially in low cooling rates. In the present work, we put an emphasis

Microstructural Characterization and Mechanical Properties of Direct Quenched and Partitioned High-Aluminum and High-Silicon Steels

Metals, 2019
A new experimental steel containing in weight percent 0.3C-2.0Mn-0.5Si-1.0Al-2.2Cr and 0.3C-1.9Mn-1.0Si-1.0Cr was hot rolled in a laboratory rolling mill and directly quenched within the martensite start and finish temperature range.

Field dependent neutron diffraction study in Ni50Mn38Sb12 Heusler alloy [PDF]

Applied Physics Letters 110, 021902 (2017), 2017
In this paper, we present temperature and field dependent neutron diffraction (ND) study to unravel the structural and the magnetic properties in Ni50Mn38Sb12 Heusler system. This alloy shows martensitic transition from high temperature austenite cubic phase to low temperature martensite orthorhombic phase on cooling. At 3 K, the lattice parameters and

Stress-Induced Phase Transformation and Its Correlation with Corrosion Properties of Dual-Phase High Carbon Steel

Journal of Manufacturing and Materials Processing, 2019
It is well known that stress-induced phase transformation in dual-phase steel leads to the degradation of bulk corrosion resistance properties. Predicting this behaviour in high carbon steel is imperative for designing this grade of steel for more ...

Influence of intermartensitic transitions on transport properties of Ni2.16Mn0.84Ga alloy [PDF]

J. Phys.: Condens. Matter 16 (2004), pp. 1951-1961, 2004
Magnetic, transport, and x-ray diffraction measurements of ferromagnetic shape memory alloy Ni$_{2.16}$Mn$_{0.84}$Ga revealed that this alloy undergoes an intermartensitic transition upon cooling, whereas no such a transition is observed upon subsequent heating.
