Abstract The work presents results on the effect of prior martensite formation bainite transformation kinetics in a 3% medium-Mn multiphase steel. material was subjected to two isothermal holding temperatures: 400 °C (without martensite) and 350 (with martensite). According obtained dilatometric results, leads acceleration kinetics. starts finishes much faster, when present before holding. micr...

In the present study, isothermal decomposition of austenite to bainite in 1.0 wt% carbon, 0.21% silicon steel during partitioning step a quenching and (Q&P) heat treatment has been investigated dilatometer temperature range 200 350 °C compared conventional austempering treatment. The transformation was shortened by about 75% presence pre-existing martensite (QP). kinetics is described well-...

Three phase supply is available in the generating station or grid, were as nine phase supply is required for many industrial applications such as, aerospace, railway and automobile applications. There are different methods in which we can convert 3 to 9 phase using 18-Pulse Converter, Carrier Based PWM Technique, multilevel converter and Multiphase Transformer. The above said methods which are ...

In the present study, an improved multiphase field model with taking into consideration S/L interface anisotropy is proposed to simulate dendritic growth peritectic transition of low-carbon steel, and a new random heterogeneous nucleation method treat γ phase during solidification process. The around dendrite (the single polycrystalline ferrite) subsequent transformation are simulated. results ...

In this paper, the internal structure of novel multiphase gallium nitride nanowires in which multiple zinc-blende and wurtzite crystalline domains grow simultaneously along the entire length of the nanowire is investigated. Orientation relationships within the multiphase nanowires are identified using high-resolution transmission electron microscopy of nanowire cross-sections fabricated with a ...

Multiphase waterborne polymer particles provide advantages in more demanding applications, and their performance depends on particle morphology. Currently, no dynamic model for the prediction of the development of the morphology of multiphase latex particles is available. In this work, a model was developed for the prediction of the dynamic development of the morphology of multiphase waterborne...
