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

Effect of lattice mismatch-induced strains on coupled diffusive and displacive phase transformations
, 2006 Materials which can undergo slow diffusive transformations as well as fast displacive transformations are studied using the phase-field method. The model captures the essential features of the time-temperature-transformation (TTT) diagrams, continuous ...

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 ...

Coherent phonon dynamics at the martensitic phase transition of Ni_2MnGa [PDF]
, 2012 We use time-resolved optical reflectivity to study the laser stimulated dynamics in the magnetic shape memory alloy Ni_2MnGa. We observe two coherent optical phonons, at 1.2 THz in the martensite phase and at 0.7 THz in the pre-martensite phase, which we interpret as a zone-folded acoustic phonon and a heavily damped amplitudon respectively.

Modulated Martensite: Why it forms and why it deforms easily [PDF]
New Journal of Physics 13 (2011) 053029, 2010 Diffusionless phase transitions are at the core of the multifunctionality of (magnetic) shape memory alloys, ferroelectrics and multiferroics. Giant strain effects under external fields are obtained in low symmetric modulated martensitic phases. We outline the origin of modulated phases, their connection with tetragonal martensite and consequences for ...
