Abstract: We experimentally investigated changes to the titanium concentrations of quartz-rich rocks caused by grain-boundary migration. Synthesis experiments were performed to make high-Ti quartz starting materials for usage in recrystallization experiments. We isothermally recrystallized quartz starting… read more here.

Abstract: The Cu-Ni-Si alloy is known as a precipitation hardening alloy, where the Ni2Si intermetallic compound is precipitated in the matrix during aging. There are two types of precipitation of Ni2Si: continuous and discontinuous cellular. The… read more here.

DOI: 10.1017/s1431927617011862
Abstract: Welded joints of multicomponent alloys when submitted to high temperatures close to operating conditions are very susceptible to grain boundary precipitation, thereby reducing both corrosion resistance and mechanical properties [1]. We focus our attention here… read more here.
