Abstract Scope |
During Spark Plasma Sintering, a correlation between the densification kinetics and compressive creep has been analyzed as creep was the main mechanism occurring in the densification final stage. After analyzing the parameters, it was found that they were in good agreement with those obtained from conventional creep experiments. In that sense, an SPS apparatus has been recently used as a creep testing system at higher temperatures than the limit of conventional creep testing apparatuses. Utilizing a special mold configuration, the creep behavior of AlZrCrMoNbTi high entropy alloy has been tested at several high temperatures and pressures that leads to the calculation of creep parameters, which are the activation energy and the stress exponent. As a result, The capability of SPS to be used as a creep test system provides access to obtaining the high temperature creep behavior of materials that will potentially be used in high temperature environments. |
