The dynamic behavior of three high manganese steels with very different stacking faultenergy (SFE) values (4-30 mJ/m2) were studied using high strain rate torsional tests. The hotrolledmicrostructure of the steel with the lowest SFE of 4 mJ/m2 consisted of a duplex mixture ofaustenite and ε-martensite, but those of the other two steels were fully austenitic. The deformedmicrostructures were stu...

Mechanochemical treatment, or high energy ball milling, was successfully employed to destroy per- and polyfluoroalkyl substances in an aqueous film-forming foam concentrate authentic contaminated soil sample.

hdpe monofilaments were obtained using different extruders and drawn by post-extruder equipments. after solidification, drawn and undrawn monofilaments (draw ratio 7:1) were irradiated with 10 mev electron beams in air at room temperature at 25, 50, 75, 100 and 125 kgy dose ranges to induce a network structure. hdpe crosslinking was studied on the basis of gel content measurements. the fibers w...

Laser flexible shock micro-bulging (LFSB) is a novel micro fabrication technology, which combines laser dynamic forming and flexible die forming, which is a type of high strain rate micro-forming. The LFSB of 304 stainless steel foils was investigated in this paper. Experimental and simulated results indicated that the bulging depth and thickness thinning rate of bulging parts increased with an...

Two-temperature models are used to represent the interaction between atoms and free electrons during thermal transients such as radiation damage, laser heating, and cascade simulations. In this paper, we introduce an energy-conserving version of an inhomogeneous finite reservoir two-temperature model using a Langevin thermostat to communicate energy between the electronic and atomic subsystems....
