Ultra-Fine Grained Dual-Phase Steels
This paper provides an overview on obtaining low-carbon ultra-fine grained dual-phase steels through rapid intercritical annealing of cold-rolled sheet as improved materials for automotive applications. A laboratory processing route was designed that involves cold-rolling of a tempered martensite structure followed by a second tempering step to produce a fine grained aggregate of ferrite and ca...

متن کاملOptimized production route of WC powder pre-alloyed with Ta for fine grained cemented carbides
Article history: Received 30 March 2016 Received in revised form 13 May 2016 Accepted 22 May 2016 Available online 24 May 2016 Powders of hexagonal (W,Ta)Cwere produced following a two-step carburization processwith (W,Ta)2C powder as an intermediate product. XRD measurements indicate that higher temperatures during the first carburization step increase the fraction of Ta in the (W,Ta)2C struct...

متن کاملGrinding effects on surface integrity and mechanical strength of WC-Co cemented carbides
In this study, the correlation existing among grinding, surface integrity, and flexural strength is investigated for WC-Co cemented carbides (hardmetals). A fine-grained WC-13 wt % Co grade and three different surface conditions: (1) ground, (2) mirror-like polished (reference), and (3) ground plus high-temperature annealed, are investigated. Surface integrity and mechanical characterization is...
