To be noted is that for some alloy steels, amount of draft should also be within the formability limit to avoid possible crack.

應(yīng)當(dāng)指出的是杏花三月天在线观看免费，一些合金鋼裸体美女被操黄色网站，變形量也應(yīng)在變形程度極限以?xún)?nèi)，以避免可能的斷裂在线毛片视频不卡。

For example, biaxial orientation of PET or polystyrene film ensures improved strength and formability.

舉例來(lái)說(shuō)免费A级视频在线，雙軸取向的PET或聚苯乙烯薄膜確保改善強(qiáng)度和成形性。

However, magnesium alloys have poor formability due to the hexagonal close-packed crystal structure.

但是欧美99操逼，鎂合金大多具有密排六方結(jié)構(gòu)黄色网站在线观看无码，傳統(tǒng)上一直被認(rèn)為是一種難以塑性變形、壓力加工成形性能差的金屬材料欧美大屌强奸视频。

However, magnesium alloyshave poor formability and limited ductility at room temperature ascribed totheir hexagonal close-packed crystal structure.

目前熱處理細(xì)化晶粒成為提高鎂合金塑性的一種有效手段欧美性爱观看视频，但是研究工作多集中在鑄造態(tài)鎂合金，關(guān)于擠壓態(tài)鎂合金型材的研究很少玖久在线观看黄色网站免费。

But magnesium alloy has a hexagonal close-packed crystal structure with limited number of operative slip systems at room temperature, so magnesium alloys are normally low formability near the room temperature, and limits the expansion of magnesium alloy applications.

但是由于鎂合金是密排六方結(jié)構(gòu)亚洲加勒比无码一区二区，可開(kāi)動(dòng)的滑移系比面心立方和體心立方金屬的少，使得鎂合金的室溫塑性較低好吊丝袜免费观看视频，降低了成形能力出处男女视频网站，限制了變形鎂合金的推廣應(yīng)用。

Firstly, with the help of Contour Map and Expansion Ratio, formability analysis can be done in point of geometry.

本文通過(guò)等高面分析亚洲速播18禁久久久久久、成形度分析等方法從幾何角度進(jìn)行覆蓋件拉延成形性分析操逼网2020。

It is shown that compared to conventional HSLA steel, DP steel and TRIP steel have relatively higher ability to ensure the strain distribution much evener and obtain much higher formability, which will improve the part strengths remarkably.

研究結(jié)果表明国产在线专区，與傳統(tǒng)HSLA鋼板相比，DP鋼和TRIP鋼具有較好的應(yīng)變均化能力美女视频黄色网站免费看，和較高的成形性亚洲三级片国产AV，有利于提高零件的使用強(qiáng)度。

Aging always has a negative effect on formability and, when aging leads to the redevelopment of an upper yield point, can result in renewed susceptibility to fluting.

在可鑄性方面涩涩视频免费观看，老化反應(yīng)總是會(huì)起到負(fù)面作用美女的私密秘网站，當(dāng)老化足以重新恢復(fù)較高的屈服點(diǎn)時(shí)，將會(huì)引起磁化系數(shù)更新人人操人人骚，形成凹槽97久久久久人妻碰碰碰碰。

Although ceramics may have good strength and hardness, their ductility, formability, and shock resistance are poor.

雖然陶瓷也許有好力量和堅(jiān)硬，他們的延展性一二三四日本高清视频动漫、formability找个av网站，和震動(dòng)抵抗是窮的。

The influencing factor analysis shows that the formability window obviously expands with the decreasing of the drawing ratio and the increasing of the normal anisotropical coefficient r -value and the die profile radius, but the effect of the hardening exponent n -value on formability window is not obvious.

而影響因素分析顯示：隨著拉深比降低曰韩性爱无码无毛片儿、厚向異性系數(shù)增加和凹模圓角半徑增大伊人久久久超碰国产一卡二卡，成形窗口明顯擴(kuò)大； n 值增加人人射色综合网，成形窗口雖然有所擴(kuò)大亚洲曰本无码av中文字幕，但是效果并不明顯。
