In this purpose, <b>two original aspects<\/b> will be approached: (i) <b><i>the relationship MA\u2019d fraction\u2011SIM monovariant domain size<\/i><\/b> and (ii) <b><i>the interaction between PM-MA\u2019d Fe-Mn-Si-Cr-Ni SMAs grain size\/ porosity and SIM reversion to austenite<\/i><\/b>. The combination of two well-known processing techniques &#8211; PM and MA &#8211; with common treatment techniques for Fe-Mn-Si-Cr-Ni SMAs &#8211; hot rolling, heat treatment, pre-straining &#8211; is meant to develop a <b><i>novel manufacturing procedure for training-free Fe\u2013Mn\u2013Si base SMAs<\/i><\/b> with improved recovery stress, prone for <b><i>further extension of the applications of these alloys in other engineering areas<\/i><\/b>. By considering that PM-MA processing of Fe-Mn-Si-Cr-Ni SMAs requires rather large time and material resources (25 specimens with given MA\u2019d fraction will be produced in a single stage, for each of the first 5 research objective) and that acquiring new expensive research equipment, according to Romanian acquisition system, sometimes involves unexpected intricate delaying procedures (contestations), project\u2019s objectives have been formulated as follows:<\/p>\n<p style=\"text-align: justify;\">1.

Emphasizing the reversible formation of SIM in hot rolled heat treated pre-stressed Fe-Mn-Si-Cr-Ni SMA specimens sintered from mixtures of as blended and 10 % MA\u2019d powders (<i>10_MA<\/i>);<\/p>\n<p style=\"text-align: justify;\">3.
