TL;DR: In this paper, the detailed microstructure and tensile properties of as-cast and heat-treated new experimental alloy belonging to cast Al-Si near-eutectic alloys have been investigated as a function of Fe, Mn, Cu, and Mg content.

TL;DR: In this article, it was found that bonds formed by brazing with aluminium at 1000 °C could have shear strengths as great as 60MPa, which suggested that good brazings systems could be developed.
Abstract: Several series of experiments have been conducted to gain information about the wettability of AlN, BN, Si3N4 and two sialon ceramics by potential braze materials. It was possible to achieve wetting of all five ceramics using aluminium, copper-titanium alloys, and a Ag-28Cu-2Ti alloy. Wetting by aluminium and the Ag-28Cu-2Ti alloy was usually good. Both wetting and non-wetting alloys containing titanium reacted to form TiN and it is argued that the achievement of wettability is associated with a certain degree of hypostoichiometry. While aluminium should also have reacted, no clear evidence was obtained. In supplementary experiments it was found that bonds formed by brazing with aluminium at 1000 °C could have shear strengths as great as 60MPa. Although the experimental work was preliminary in nature, it suggested that good brazing systems could be developed.

TL;DR: A growth model of the passive films on Alloy 690 in high-temperature alkaline environments is proposed and discussed in this paper, where the authors show a duplex structure including an inner layer of fine-grained Cr oxide or spinet oxide and an outer layer of Ni-Fe spinel oxide and Ni hydroxide.

TL;DR: In this paper, an Al-Zn-Mg-Cu alloy (AA7075) was processed by high pressure torsion (HPT) at room temperature and 200°C, with an objective to reveal the deformation-induced precipitation and segregation of elements at grain boundaries.
