Quenched and Partitioned Steel Wires: Process, Characterization, and Properties

Quenched and Partitioned Steel Wires: Process, Characterization, and Properties

$15.00

Steel wires with a microstructure containing martensite and retained austenite were produced with the Quenching and Partitioning (Q&P) thermal process, a modified version of the Quenching and Tempering (Q&T) process. The Q&P wires exhibited high “total elongation – at” x “tensile strength – N/mm²” product, above 20000 %. N/mm². This multiplication product is two to three times higher than with Q&T. The higher elongation was due to the TRIP (Transformation Induced Plasticity) effect during plastic deformation. The results reveal application possibilities especially where high energy absorption behavior is required.
