Alloys of CuAlMn are known as cheap, high strength shape memory alloys with an excellent damping capacity within their austenitic-martensitic phase transformation, compared to

A higher scanning speed provides a lower laser interaction time with the surface of the samples, and thus, a lower fraction of material is remelted culminating with lower

The appearance of BCT martensite in Fe-Pd-based ferromagnetic shape memory alloys, which develops at lower temperatures than the thermoelastic martensitic transition,

Thought TIG has a higher heat input it has some similarities to conduction laser weld mode since there is no filler material and an inert gas is used.. Additionally,

That is not the case for Cu-Al-Mn shape memory alloys that do not appear to exhibit significant changes on the overall tensile properties of the welded joints, when compared

The device is able to dissipate a considerable amount of energy, while minimizing a set of adverse effects, related with cyclic loading and aging effects, that hinder the

The reason why sample C-C shows a higher accumulated irrecoverable strain when compared to sample A-A and B-B for the same number of cycles may be explained as follows: although
