High-temperature quality of accelerated spheroidization on SUP9 leaf spring to enhance machinability

Heliyon, 2018
The high temperature on the austenitization showed the varied results in the fast spheroidization in high carbon leaf spring steel SUP9/55CrMnA. The heating temperature was held for 15 minutes in the austenitization temperature at 800, 850, and 900 °C ...

The design of an Fe-12Mn-O.2Ti alloy steel for low temperature use [PDF]

An investigation was made to improve the low temperature mechanical properties of Fe-8 approximately 12% Mn-O 2Ti alloy steels. A two-phase(alpha + gamma) tempering in combination with cold working or hot working was identified as an effective treatment.

The Influence of Rapid Tempering on the Mechanical and Microstructural Characteristics of 51CrV4 Steel

Metals
The microstructure and mechanical properties of a low-alloy medium carbon steel (Fe-0.5C-0.9Mn-1Cr-0.16V, in wt.%) were investigated after rapid tempering and compared with a conventionally tempered counterpart.

The Digital Image Correlation technique applied to the deformation behavior of welded sheet joints [PDF]

, 2013
The existence of a welded zone generally influences the local strain and stress distribution especially in case of welding defects. A method able to measure the local deformability can hence give many important information about the real stress and ...

A prediction model for austenite grain size distribution of casting slab in thermal rebound process: Considering α-ferrite precipitation and re-austenization

Journal of Materials Research and Technology
The precipitation and re-austenitization behavior of α-ferrite during thermal rebound process of casting slab are crucial to the austenite grain size distribution. Accurately obtaining austenite grain size distribution plays an important guiding role for

Prediction of critical cooling rate under rapid heating rate and short holding time for pearlitic rail steel

Journal of Materials Research and Technology
Critical cooling rate (Vc) is typically employed to assess the ability of forming martensite for pearlitic railway steels. Currently, the examination of Vc is normally conducted by dilatometry analysis under a fully austenitizing condition.
