Temperature Effects on the Strength and Toughness of $ Be_{12} $Nb
Abstract Strength and toughness of single-phase $ Be_{12} $Nb have been assessed at temperatures from ambient to 1200 C using four-point-bend and hardness tests. Vacuum-hot-pressed beryllide exhibits low bend strengths (~110 MPa) and fracture toughnesses (~2.5MPa√m) at temperatures up to 500 C. Meas...

Temperature Effects on the Strength and Toughness of $ Be_{12} $Nb |
| abstract |
Abstract Strength and toughness of single-phase $ Be_{12} $Nb have been assessed at temperatures from ambient to 1200 C using four-point-bend and hardness tests. Vacuum-hot-pressed beryllide exhibits low bend strengths (~110 MPa) and fracture toughnesses (~2.5MPa√m) at temperatures up to 500 C. Measured bend strength then increases to a maximum at 1000 C, while $ K_{IC} $ slowly increases through 1100 C. Significant plastic deformation is only observed at 1200 C for the test strain rate of $ 2X10^{-6} $/s. Hardness values were found to remain relatively constant at temperatures up to 800 C and then sharply decrease at higher temperatures. Results indicate that low toughness limits bend strength at temperatures below ~1000 C and prompts the observed increase in strength at high temperatures. |

Abstract Strength and toughness of single-phase $ Be_{12} $Nb have been assessed at temperatures from ambient to 1200 C using four-point-bend and hardness tests. Vacuum-hot-pressed beryllide exhibits low bend strengths (~110 MPa) and fracture toughnesses (~2.5MPa√m) at temperatures up to 500 C. Measured bend strength then increases to a maximum at 1000 C, while $ K_{IC} $ slowly increases through 1100 C. Significant plastic deformation is only observed at 1200 C for the test strain rate of $ 2X10^{-6} $/s. Hardness values were found to remain relatively constant at temperatures up to 800 C and then sharply decrease at higher temperatures. Results indicate that low toughness limits bend strength at temperatures below ~1000 C and prompts the observed increase in strength at high temperatures. |
