Weight-Preserving Simulated Tempering [PDF]
, 2019 Simulated tempering is popular method of allowing MCMC algorithms to move between modes of a multimodal target density {\pi}. One problem with simulated tempering for multimodal targets is that the weights of the various modes change for different ...

Retained Austenite Destabilization during Tempering of Low-Temperature Bainite
Applied Sciences, 2020 The thermal stability of nanostructured microstructures consisting of a mixture of bainitic ferrite and carbon-enriched retained austenite has been studied in two steels containing 0.6 C (wt %) by tempering cycles of 1 h at temperatures ranging from 450 ...

Simulated tempering: a new Monte Carlo scheme [PDF]
, 1992 We propose a new global optimization method (Simulated Tempering) for simulating effectively a system with a rough free-energy landscape (i.e., many coexisting states) at finite nonzero temperature. This method is related to simulated annealing, but here

Journal of Materials Research and Technology, 2022 A single-bead multilayer martensitic stainless steel thin wall was fabricated using the wire arc additive manufacturing (WAAM) process. After the WAAM process, the tempering heat treatment was carried out to homogenize the microstructure distribution in ...

Assessment of AISI 431Grade Stainless Steel properties by Vacuum Tempering Process
E3S Web of Conferences, 2020 The wear behaviour of AISI 431 stainless steel was examined under a dry sliding touch at compatible load with the vacuum tempering cycle. The method adopted was found to be effective in enhancing the wear conduct of stainless steel products, there by ...
