White and dark layer formation mechanism in hard cutting of AISI52100 steel
TL;DR: In this article, the microstructure, phase components, carbon distribution, and hardness of the white and dark layers of AISI 52100 steel with PCBN inserts were analyzed via scanning electron microscopy, X-ray diffraction, electron probe microanalysis, nanoindentation, and transmission electron microscope.

Small-angle neutron scattering analysis of the precipitation behaviour in a maraging steel
TL;DR: In this paper, small-angle neutron scattering (SANS) was used in addition to transmission electron microscopy (TEM) to determine precipitate size distributions and volume fractions and concluded that the precipitates consist of the intermetallic Ti6Si7Ni16 phase.

Abrasive tool containing coated superabrasive grain
TL;DR: In this paper, an abrasive grit is made by mixing the first active powder component in a liquid binder to form an adhesive paste; mixing the paste with the abrasive grains to wet the grains, and drying the mixture to adhere active component to the grains.

Classification of microstructural changes in laser hardened steel surfaces
TL;DR: In this paper, a systematic study of the changes in microstructure of these laser-affected zones, the effective hardening mechanisms were separated and their influence on the material strength or the microhardness was classified.
