The blood relationship between massive transformation and bainite transformation in steel——Further discussion of the shear-diffusion integrated mechanism of bainite transformation;

A new appraise of the doctrine of martensitic shear

Based on the fact that carbon-depleted regions come into being during the incubation period,thermodynamic models of diffusion and shear for weld acicular ferrite(AF)transformation in carbon-depleted regions of austenite were established respectively by using KRC(Kaufman,Radcliffe,Cohen)activity model and super-element algorithm,and used in the numerical simulation of a certain microalloy steel.

To correct the limitation of SHI et al's method on calculating martensitic transformation shear angle and acquire right modification of surface relief angle,Fe-25Mn-6Si-5Cr alloy was taken as an example and its surface relief angles caused by stress-induced γ(fcc)→ε(hcp) transformation were measured by(atomic) force microscope.

The variable scale cutting control system based on PLC;

The application of the series of FX2N PLC in the numerical control cutting line was proposed in this paper,and by using frequency conversion 、sensor、and the series of MR-J2 servo motor it realizes the high precision variable scale cutting of silicon steel and puts emphasis on the organization process of F940GOT.
