    金屬機械拉力試驗


    在拉力試驗時間測定許多足以判斷所試驗材料的強度和塑性的機械性能數字。在很多情況下,由拉力試驗求得的機械性能數字可以相當精確地判斷材料在其他變形的時候,例如在壓縮、扭轉、剪切和彎曲時候的性能。

    用慢慢增加的拉力載荷加在有標準的形狀和尺寸的試樣上,觀察由于這種載荷作用所產生的彈性變形和永久變形。在拉力試驗的時候,求取下列機械性能數字:

    1)對微小的塑形變形的抵抗能力;這種性能常常用比例極限和屈服極點來說明。

    2)對微小的塑形變形的抵抗能力;這種性能能用拉力下的強度極限來說明。

    3)塑形,就是到破裂為止的塑形變形的大小;這種性能用相對伸長度和斷面相對縮小度來說明。

    在拉力試驗的時候,在均勻增加的載荷下,圓柱形或菱形的試件發生了變形,一直到斷掉為止。一般試驗機都擁有機圈裝置,在試驗的進行過程中,可以用它來自動機出拉力圈;這種拉力圈把作用在試樣上的力和因此引起的變形之間的關系顯示出來。

    在試樣的試驗過程中,彈性變形和塑形變形可以在拉力圈上根特殊的線段和電子來決定。在線段上,試樣的伸長度跟載荷成正比地增加,這一關系,跟材料力學的幾班定理----比例定理吻合。根據這一定律,實驗上載荷的改變,在連接到某一限度以前,會引起試樣變形成比例的改變。

    在拉力實驗中,載荷跟伸長度之間能保持直線間隙的最大載荷叫做比例極限的載荷。應該指出,在試驗的保障條件下,圈的開始地方一般都有一段不大的曲線部分,這是試樣在拉力試驗的夾頭中有滑動的結果。在載荷增加到高出的時候,拉力曲線稍稍偏離了直線,試樣在彈性變形的同時,開始得到了很小的永久變形。

    載荷在習慣上一般叫做彈性極限的載荷,在這一載荷下試樣得到的永久伸長度等于它自己的原有長度的0.005%。載載荷曲線轉變為水平線段,在這一線段上,試樣的材料在拉伸試驗的里沒有增加的情況下,有了相當大的永久伸長度,試樣好像停止了對拉力給以抵抗能力,也就是好像流動起來了。

    在它的作用下材料開始流動的載荷,叫做屈服點載荷,而曲線的水平線段,相當于載荷沒有增加的情況下的試樣伸長度,叫做屈服線段。

    材料的塑性變形的結果,在試樣表面上出現了所謂滑移線紋,它跟試樣中心線傾斜,成為約45°左右的角度;這些線紋是由于切應力在材料內部英氣結晶體的滑移而產生的。滑移線紋是切關諾夫首先在過度鋼板上發現的,這些線紋的數量跟著屈服線段的進行而增加,由于他們使試樣的光亮的表面發暗而改變得沒有了光澤了。

    在屈服階段之后,載荷重新增加,練到某一最大值;在這以后,開始生成局部縮小的斷面,既所謂細頭,細頭范圍內的斷面逐漸縮小,載荷也因此下降,而在p2點時間發生了試樣的斷裂。

    開始生成細頭以后,試樣此后的伸長主要發生在細頭的一段時間長度內,試樣的其他部分實際上并不伸長。

    在斷裂的瞬間,試樣的總變形(彈性的和永久的)等于線段OD的大小。

    為了求取在斷裂的瞬間內試樣的彈性變形和永久變形的大小期間,必須在拉力圈上從P點引直線平行于曲線上的直線部分,一直到跟橫坐標相交為止,線段OC代表永久變形的大小,線段CD則代表完全彈性變形的大笑。

    這種確定彈性變形和永久變形的方法正確性很容易用試驗來證明:如果從試樣已經發生永久變形以后的任意一點慢慢地把試樣上的載荷卸掉,那么載荷卸除曲線就成為在線的樣子跟他平行。
