Abstract: Crystallization temperature of the metallic glass Zr_(70)Cu_(30),observed by X-ray diffraction analysis,may be increased about 20℃,the superior limit of increase range of the temperature is about 30℃,under high pressure up to 2GPa.Besides α-Zr and CuZr_2, the Cu_(10)Zr_7 phase was newly obtained as another crystallization product.

Key words: metallic glass Zr_(70)CU_(30), crystallization, high pressure
