We study the mechanical properties of Mg–Li alloys obtained by high-pressure die casting in a cold pressing chamber. A procedure of evaluation of the principal strength characteristics obtained under the conditions of high plastic strains is presented. The fracture toughness of materials under quasistatic and dynamic concentrated loads is investigated.
