查询词典 brittleness

It is shown that nanoscale pyramid cone shapes are found on the metal film interface (100), serrate steps are found on the metal film interface (111), and cystiform shapes with terrace structure are found on the cross-section near the catalyst. Other faults have brittleness fracture characteristic with nanoscale clusters are found on the fault surface.

However, due to the issue of brittleness of ceramics and its manufacturing technology. the happing lost ceramics. crack inside and interface separate often occur clinically .In this regard, it not only delay the restoration, but also greatly add the expense of restoration. Hence, an inspection method is required to develop.

但是由于陶瓷的脆性和制作工艺的问题，临床中经常出现脱瓷、内部出现裂痕或界面脱落等情况，不仅延长了口腔金瓷修复的时间，而且使修复的费用大大增加，因此需要一种检测方法，在修复前或修复后都能判断金瓷牙齿表面或内部是否存在缺陷。

However, due to the issue of brittleness of ceramics and its manufacturing technology, the happing lost ceramics, crack inside and interface separate often occur clinically. In this regard, it not only delay the restoration, but also greatly add the expense of restoration. Hence, an inspection method is required to develop, in order to judge whether there is flaw on the PFM teeth cover or inside both before and after restoration.

As the brittleness of low-k material,the traditional wire bonding parameter often lead to die pad crack or Au-AL matter bad;after used low-k material,die size,die pad opening and die pad pitch change to more little,wire change to lengther and density change to more higher,it\' s new challenge for molding and wire bonding;at the same time, low-k material also require to control the thermal stress in package.

由于低介电常数材料的脆性，传统的引线压焊参数设置将会导致焊盘碎裂以及金铝化合物不良；由于使用低介电常数材料后，芯片尺寸、压焊区域和压焊间距进一步减小，金线压焊长度和密度大大增加，这就为压焊和模塑提出了新的要求；同样由于低介电常数材料的应用，对封装体内部的热应力的控制也提出了更高的要求。

The results show that, Au-19.25Ag-12.80Ge brazing alloy is better, its melting temperature range is 446.76494.40 ℃, and the temperature interval between the solidus and the liquidus is 47.64 ℃. When the brazing temperature is in the range of 510550 ℃, the alloy has a good spreadability and wettability with Ni. Interface structure observation reveals that there is one continuous intermetallic layer between the brazing alloy and the base metal Ni when welding. X-ray energy spectrum analysis results show that the intermetallic layer is Ge3Ni5, and because of its brittleness, the overthick intermetallic layer will decrease the shear strength of the welding joint, therefore, the welding technology should be controlled so as to gain an ideal welding interface structure.

研究结果表明：Au-19.25Ag-12.80Ge合金的性能较好，其熔化温度范围为446.76~494.40 ℃，结晶温度区间为47.64 ℃；焊接温度在510~550 ℃范围内时，Au-19.25Ag-12.80Ge钎料合金与Ni基体具有良好的铺展性和润湿性，焊接时钎料合金与Ni基体之间形成了一条连续的金属间化合物层，能谱分析表明该金属间化合物层为Ge3Ni5，由于该化合物较脆，过厚的金属间化合物层使焊接接头的剪切强度下降，故应适当控制焊接工艺以获得理想的焊接界面组织。
