Low Young's modulus is one of the attractive features of metastable Ti alloys.Young's modulus is closely related with the martensitic transformation in many shape memory alloys including Ti alloys.This is because both the elastic constants and martensitic transformation temperature are closely related to the lattice stability.Young's Modulus - University of WashingtonThe Young's Modulus of a material is a fundamental property of every material that cannot be changed.It is dependent upon temperature and pressure however.The Young's Modulus (or Elastic Modulus) is in essence the stiffness of a material.In other words,it is how easily it is bended or stretched.What is Youngs Modulus? - Service ThreadA high modulus yarn can withstand more initial force,even under repeated bouts of pressure and release,without showing permanent deformity of its shape.A low modulus yarn isnt as resilient.Even when the force subsides,the low-modulus material has a hard time recovering and snapping right back into shape.
