The tuning of Heusler alloys with respect to its stoichiometry and its effect on martensitic transformation have been investigated very little by various researchers. Thus, the effect of change in Ferrous (Fe) concentration of the alloys and its effect on mechanical and magnetocaloric properties of Ni50-xFexMn30Sn20-yIny alloys were investigated where Fe is varied from x= 1, 2, 3 and 4 finds its significance. Increase of Fe concentration to Fe4 leads to a considerable improvement in the alloy's mechanical properties and crystal structure. Compressive strength of the alloy rose by 123 % for Fe4 substitution. When comparing the identical materials with and without Fe addition, the ultimate stress (US) and ductility improve by 124 and 200 %, respectively, while toughness rises by 48 times. The Fe concentration variation also enabled a martensitic transformation in 36.8 to 19.83 °C range of refrigerator applications.
