High-strength, low-alloy (HSLA) steel has attracted much attention in the manufacturing industry because of its good combination high strength and toughness, low cost, formability. Wire arc additive (WAAM) technology can realize rapid prototyping HSLA parts. This study investigated a 26-layer component fabricated with WAAM technique. The microstructure deposited wall ER120S-G is mainly acicular...

Ruiz, PEMSA Co. Celaya, Guanajuato, México. The eff ect of initial plastic strain c ycle fatigue lives of HSLA specimens is in vestigated. Specimens were monotonically, quasi-statically loaded under strain...

This work demonstrates a novel application of ultrasound: measurement of magnetostriction, the change of length of a ferromagnetic material that accompanies a change in magnetization. The technique involves measuring ultrasonic waves generated by an electromagnetic acoustic transducer (EMAT), and it offers an alternative method of measuring magnetostriction in cases where it would not be feasib...
