The influence of visco-elastic processes on the generation of thermal stresses in quenched low alloy steel plates.
… although an air cool following an intermediate salt bath treatment above the Ms temperature prevented the generation of thermal stresses during the formation of martensite. The use of an oil quench following the salt bath treatment was of no value, and none of the combinations of heat treatment …

Analysis of Strength Variation in Glass Due to Ion Exchange
… heat treatment with and without an ion exchange bath. Several sample groups of 30 sodium borosilicate glass rod specimens were heat treated at various temperatures in air and in a potassium nitrate salt bath to induce an ion exchange process. All samples were then tested to failure in 4-point …

The Effects of Applied Strain and Heat Treatment on the Properties of NiTi Wire During Shape Setting
… wire under applied strain were heat treated in a salt bath, followed by a rapid quench. Transformation temperatures and mechanical properties were characterized using the differential scanning calorimeter and tensile tests. Changes in the Af, UTS, and elastic modulus due to ageing processes and …

Development Of High Strength High Toughness Third Generation Advanced High Strength Steels.
… was carried out for 2 hours in a molten salt bath. The microstructures were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy and optical metallography. Quantitative analysis was carried out by image analysis technique. The effect of …

Retrogression-reaging and hot forming of AA7075
… 30 minutes. RRA behavior was studied with molten salt bath treatments between 200 and 350 °C. The PBC was used in lieu of the standard 24 hour reaging treatment conducted at 121 °C. It was determined that retrogression treating below 250 °C was acceptable for RRA forming, with retrogressing at 200 …

A study of the microstructural and mechanical properties of novel spring steels.
… further, namely a chromium molybdenum alloy, salt bath quenched to produce a bainitic microstructure, a water quenched low carbon chromium and low carbon boron martensitic type alloy. The low carbon boron alloy was considered the most promising, with similar mechanical properties in both the …

Filling flows induced by a convector in a room
Over the last two centuries, there has been a continual evolution of how occupied rooms are heated, with inventors competing to design new heating devices. In particular, there is a wide range of convector types, which vary in shape, size, design, material, operating medium and application. With …
