(University of Pretoria, 2016)The feasibility of in-situ alloying of AISI 410L martensitic stainless steel with nitrogen during Nd-YAG laser cladding was investigated with the aim of achieving a nitrogen content of at least 0.08 wt% and fully martensitic ...
-
(University of Pretoria, 2018)Compared to conventional arc welding processes, laser metal deposition is a low heat input, low dilution welding process. Weld overlay of thin wall components can be done successfully with low distortion and low dilution, ...
-
(University of Pretoria, 2019)The service performance of zirconium-2.5niobium components is largely dependent on the microstructure and mechanical properties achieved through a specific thermo-mechanical process applied during manufacturing. Welding ...
-
(University of Pretoria, 2017)Plain C-Mn steels such as SA-516 Grade 65 are used as steam lines to transport high temperature steam under pressure. Plain carbon steels that are in service at elevated temperatures (typically 400-450°C) for prolonged ...
-
(University of Pretoria, 2017)Low pressure gas carburising (LPGC) or vacuum carburising is a heat treatment process used in the aerospace and automotive industries to surface harden low alloy steel parts with carbon in the range of 0.1 to 0.25%. This ...
-
(University of Pretoria, 2015)Type 441 stainless steel (EN 1.4509 or UNS S43940) is a low carbon dual-stabilised ferritic grade with a nominal chromium content of 18%. This steel displays high corrosion and oxidation resistance, good formability, ...
-
(University of Pretoria, 2019)In the petrochemical industry, carbon steels exposed to H2S environments may be susceptible to stress-corrosion cracking. A tensile residual stress and high hardness increases the risk of cracking in H2S environments. NACE ...
