a, c Engineering stress-strain curves and fracture morphologies of samples A and B under different conditions. b The A-1200 sample mainly shows an intergranular fracture (see the red arrow), with apparent transgranular cleavage. Certain amounts of micropores with a diameter of <1 μm are observed in the transgranular-fractured grains in A-1200 sample, see the white arrow. d The sample B-1200 exhibits a feature of fibrous tearing in the center and transgranular cleavage in the outer region of the fracture surface, with much smaller cleavage planes. e Comparison of tensile strength and total elongation of different as-rolled Mo materials at room-temperature2,3,12,14,15,17,18,21,22,23,34,35,36. f Comparison of total elongation of different annealed Mo materials at room temperature3,12,14,15,17,18,21,22,23,34,35,36.
