Softening frequently occurs in dual-phase steels under isothermal tempering of martensite. Recently, non-isothermal tempering is implemented to decrease the softening process in dualphase steels. Here, we have discovered using high power electropulsing treatment can significantly enhance the strengthening effects via the formation of ultrafine-grained ferrite with nano-cementite particles in te...

Recent Bauschinger-type tests conducted on a twinning-induced plasticity (TWIP) steel highlights the important contribution of internal stresses to work hardening [1]. Along this line we present Bauschinger experiments in a Fe-22Mn wt.%-0.6C wt.% TWIP steel. The mechanical behaviour upon load reversal shows transient and permanent softening effects. Determination of the internal stress from the...

The large strain nonlinear stress-strain behavior of thermoplastic polyurethanes (TPUs) exhibits strong hysteresis, rate dependence and softening. Thermoplastic polyurethanes are copolymers composed of hard and soft segments. The hard and soft segments phase separate to form a microstructure of hard and soft domains typically on a length scale of a few tens of nanometers. Studies have revealed ...

With the rapid development of road engineering today, a large number high-grade highways need to pass through expansive soil distribution areas. At present, research on slope mainly focuses newly excavated cutting slope. However, according experience, landslide fill embankment foundation is also very common. The layer heterogeneous. There are many weak intercalations or fissures under ground, w...

Liquid-solid fluidisation is frequently encountered in drinking water treatment processes, for instance seeded crystallisation softening processes. For modest superficial fluid velocities, liquid–solid systems are generally considered to be homogeneous, as reported literature. However, during experiments with calcite grains, open spaces of can observed between the fluidised particles, even at r...

T he first programmable computers were rather nasty beasts. These giant 1940s machines occupied entire rooms and consumed kilowatts of electricity. The computation problems engineers faced more often involved failed machine hardware components than the short and mostly unchanging programs engineers fed to those machines. Engineers viewed computers and their programs as unified entities. Over th...
