| 成分 | 1.（含量-元素）However, 3%（1）Mn（2） addition leads to a substantial improvement of the tensile strengths at elevated temperature. |
| 2.（元素-合金）Effect of Fe（1） and Mn（1） additions on microstructure and mechanical properties of spray-deposition Al-20Si-3Cu-1Mg alloy（2）. |
| 实验 | 1.（合金-实验）In this paper, Al-20Si-3Cu-1Mg alloy（1） was prepared by spray deposition（2） technique. |
| 2.（实验-实验结果）Cylindrical samples（2） of 25 mm in diameter and 50 mm in length were machined out from each spray deposit obtained（1）. |
| 3.（实验-参数名）The solidification process（1） during spray-deposition occurs in two stages: gas atomization (rapid cooling)（2）and droplet consolidation (relatively slow cooling)（2）. |
| 4.（实验结果-参数名）The starting carbon particle（2） were as large as 50 mm, while the TiC particles are less than 0.7 mm in reacted preforms（1）. |
| 测试 | 1.（合金-测试名）The UTSs（2） of the TiC/Al（1） composites were improved over that of the unreinforced Al matrix |
| 2.（测试名-参数名）As shown in Table 2, the UTS（1） of the TiC/Al composites at room temperature（2） was improved over that of the unreinforced Al matrix. |
| 3.（测试名-测试值）From table 2, with additions of 5% Fe to Al-20Si-3Cu-1Mg alloy, both the yield（1） and ultimate tensile strengths（1） was increased 55（2）and 64 MPa（2） at room temperature. |
| 4.（测试名-测试图）Fig.1(c)（2） shows the scanning electron microscopy microstructure（1） of the spray-deposited A2 alloy. |
| 5.（测试名-相）The high volume fraction of metastable d-Al4FeSi2 phase（2） in the spray-deposited microstructure（1） may be attributed to two primary reasons. |
| 6.（相-测试值）The microstructure of the as-deposited alloy is composed of primary Si （1） with an average size of 12.5 µm（2） and secondary Al phase. |
| 参数 | 1.（参数名-参数值）The testing temperatures（1） were 298（2）, 473（2） and 573 K（2）. |
