warning [17]. In particular, for the pre-stress concrete structures, the risk should be strictly controlled [18, 19]. Although a hot-rolled bar used for RC structures is a type of mild steel... solution type, and stress level. To consider these factors, an experiment system was designed, as shown in Figure 4. To maintain a stable stress during the experiment, a loading device was constructed......

6(c)). There are two types of pores. One type is caused by the Kirkendall effect [43, 44], which arises because Ti consumption by TiB2 causes a decrease in volume and leads to irregular pores. The other type is spherical pores caused by indiffusable gases, e.g., Ar or O2 gas [45]; these pores remain in the specimens after cooling at RT. When the sintering time was increased to 4 h, few pores......
