Nickel based alloys capable of forming bulk metallic glass are provided. The alloys include Ni-Cr-Si-B compositions, with additions of P and Mo, and are capable of forming a metallic glass rod having a diameter of at least 1 mm. In one example of the present disclosure, the Ni-Cr-Mo-Si-B-P composition includes about 4.5 to 5 atomic percent of Cr, about 0.5 to 1 atomic percent of Mo, about 5.75 atomic percent of Si, about 11.75 atomic percent of B, about 5 atomic percent of P, and the balance is Ni, and wherein the critical metallic glass rod diameter is between 2.5 and 3 mm and the notch toughness between 55 and 65 MPa m1/2. |
