SICANE is a neutron scattering multidetector facility for the determination of the quenching factor (ratio of the response to nuclear recoils and to electrons) of cryogenic detectors used in direct WIMP searches. Well collimated monoenergetic neutron beams are obtained with inverse (p, n) reactions. The facility is described, and results obtained for the quenching factors of scintillation in Na...

Ambient and cryogenic surface mechanical attrition treatments (SMAT) are applied to bcc iron plate. Both processes result in significant surface grain refinement down to the ultrafine-grained regime; the cryogenic treatment results in a 45% greater grain size reduction. However, the refined region is shallower in the cryogenic SMAT process. The tensile ductility of the grain size gradient remai...

The effect of thermomechanical treatment, based on combination isothermal cryorolling at liquid nitrogen temperature to strains ranging from 30 90 % and subsequent single electric pulsing with an integral current density Kj up 1.6 ×104 A2 s / mm4, the structure hardness initially coarse-grained pure nickel was studied. It is shown that considered treatment quite a powerful method control Ni str...

Cryogenic treatments are increasingly used to improve the wear resistance of various steel alloys by means of transformation of retained austenite, deformation of virgin martensite and carbide refinement. In this work the nanotribological behavior and mechanical properties at the nano-scale of cryogenically and conventionally treated AISI 420 martensitic stainless steel were evaluated. Conventi...

Cr-Mn-Si alloyed high-strength steel was subjected to deep cryogenic treatment after quenching and tempering (Q-T), the microstructure property evolution of alloy were studied. The tensile strength increased by about 30 MPa, yield decreased 10 grains refined, indicating that toughness can be relatively improved via (−120 °C × 1 h); secondary carbides precipitated inside martensitic matrix unifo...

aqueous polymer quenchants are being used increasingly in steel heat treatment industries as a substitution for conventional quenchants. by adjusting the quench parameters of the polymeric media, it is possible to achieve desirable microstructure and mechanical properties in addition to reduction in distortion and cracking. in this work, polyalkylene glycol (pag) aqueous solution was used as th...
