... casting techniques. To enhance grain refinement and optimize mechanical properties, the composite undergoes T6 heat treatment. Advanced characterization methods, including optical microscopy, scanning electron microscopy (SEM), and optical profilometry, are utilized to investigate microstructural features...

... of materials. A LAM Hastelloy C22 was prepared by rotating strategy in this study, and the wear mechanism induced by heat treatment was investigated. The microstructural results showed that the columnar structure with the size of 1 ∼ 4 μm and the cellular structures with the size of 0.3 ∼ 1 μm were observed...

... that size of cementite decreased as a function of heat treatment cycle. With the increase of heat treatment cycle, the grain size of cementite in all specimens started to decrease. As a consequence, these cementite islands transformed to spherical cementite having an average grain size of 5 μ m...

...M. Abdel Aziz; T. S. Mahmoud; Z. I. Zaki; A. M. Gaafer In this article, the heat treatment and dry sliding wear behavior of Al-based AA6063 alloy reinforced with both TiC and Al 2 O 3 ceramic particles were studied. The particles were synthesized by self-propagating high temperature synthesis (SHS...

.... However, empirical evidence of a minimum life at 100% reliability has been shown for through hardened ball and spherical roller bearings, linear ball bearings, and tapered roller bearings (TRB), however, for TRB’s there is no mention as to the heat treatment nor is there a method put forth to approximate...
