1 General
1概述
The test samples shall be made from a sacrificial product or from a prolongation/extension of a product in the final solution annealed condition with locations of test specimens as defined in Table 1 representing the thickest product within the lot.Alternatively,a representative test block may be used when agreed with the purchaser.
試樣應由犧牲蜜桃视频APP入口製成,或由最終固溶退火條件下蜜桃视频APP入口的延伸/延伸製成,試樣位置如表1所示,代表批次中最厚的蜜桃视频APP入口。 或者,當與買方達成一致時,可以使用具有代表性的試塊。
Table 1-Sampling of test specimens dependent of product
表1—取決於蜜桃视频APP入口的試樣取樣
For all products,the mid-length of the test specimens shall be located one T or minimum 50 mm to any second surface provided this is feasible within the size of the test sample/sacrificial product.
對於所有蜜桃视频APP入口,試樣的中間長度應位於距離任何第二表麵一T或至少50 mm 的位置,前提是這在試樣/犧牲蜜桃视频APP入口的尺寸內是
可行的。
CVN testing is required when the wall thickness is ≥6 mm,wherever geometry permits.
當壁厚≥6mm 時,隻要幾何形狀允許,就需要進行CVN測試。
For all products,the notch axis of CVN test specimens shall be positioned perpendicular to the closest outer surface.
對於所有蜜桃视频APP入口,CVN 試樣的缺口軸線應垂直於最近的外表麵。
For welded products,two (2)sets of three(3)CVN impact toughness test specimens shall be taken from mid- thickness of the component,one(1)with notch located in base material and the other notched in the weld metal.
對於焊接蜜桃视频APP入口,應從部件的中間厚度上取兩(2)組三(3)個CVN衝擊韌性試樣,其中-(1)個缺口位於基材中,另一 個缺口位於焊接金屬中。
For forgings,HIP products and fittings,dimensioned sketches shall be established showing type,size and orientation of test specimens to betaken from a prolongation of product or a sacrificial product.
對於鍛件、HIP 蜜桃视频APP入口和配件,應建立尺寸草圖,顯示從蜜桃视频APP入口延長部分或犧牲蜜桃视频APP入口上取下的試樣的類型、尺寸和方向。
1.2 Casting test blocks
1.2鑄造試塊
Test blocks shall be integral or gated with the casting(s)they represent and shall accompany the castings through all heat treatment operations.During any heat treatment of products,which the test block
represents,the test blocks shall be tack welded onto the casting and shall accompany the castings through all heat treatment operations.Alternatively,a sacrificial product may be used as a test sample.
試塊應與其所代表的鑄件為一體或封閉式,並應伴隨鑄件進行所有熱處理操作。在蜜桃视频APP入口的任何熱處理過程中,如試塊所 示,試塊應點焊在鑄件上,並應伴隨鑄件進行所有熱處理操作。或者,可以使用犧牲蜜桃视频APP入口作為測試樣品。
The thickness of the test block shall be equal to the thickest section of the casting(s)represented.For flanged components,the largest flange thickness should be used asthe ruling section.
試塊的厚度應等於所示鑄件的最厚部分。對於法蘭部件,應使用最大的法蘭厚度作為基準截麵。
Dimensions of test blocks and locations of test specimens within the test blocks are shown in Figure 1 for
integral and gated test blocks,respectively.All test specimens shall betaken within the cross hatched area. When the thickness T of the test block is ≤50 mm,the longitudinal axis of test specimens shall be located in the centre of the test block.
圖1分別顯示了整體試塊和澆口試塊的試塊尺寸和試塊內試樣的位置。所有試樣應在交叉影線區域內進行。當試塊的厚度T≤50 mm時,試樣的縱軸應位於試塊的中心。
1.3 Welds in the as welded condition
1.3焊接狀態下的焊縫
Test specimens for weld procedure qualificationshall betaken in accordance with the requirements of ISO 15614-1 or applicable design code.
焊接工藝評定的試樣應按照ISO15614-1或適用設計規範的要求進行。
The test specimens for microstructural examinationshall comprise a cross section of the weld metal,heat affected zones and base metal of parts joined in full thickness.
用於微觀結構檢查的試樣應包括焊接金屬的橫截麵、熱影響區和全厚度連接零件的基底金屬。
The ferrite content shall be determined in the weld metal root and the last bead of the weld cap 2 mm(0,08 in)below the surface.For welds with thickness less than 5mm(0,2 in),the ferrite content shall bedetermined through the full thickness.In total,three sets of CVN test specimens shall be taken from the following
positions from the weld cap area:
鐵素體含量應在焊縫金屬根部和表麵以下2 mm(0,08 in)的焊帽最後一道焊道中確定。對於厚度小於5mm(0.2in)的焊縫,應通過整個厚度測定鐵素體含量。總共應從焊帽區域的以下位置取三組CVN試樣:
—weld metal;
一焊縫金屬;
—fusion line;
—融合線;
—fusion line+2 mm (0,08 in).
一熔合線+2毫米(0.08英寸)。
When the weld thickness exceeds 25 mm(1,0 in),two(2)additional sets of specimens shall be taken from the weld root area 2mm from the internal surface,one(1)from the weld metal and one(1)from the fusion line +2 mm (0,08 in).
當焊縫厚度超過25 mm(1.0in)時,應從距離內表麵2mm 的焊縫根部區域取兩(2)組額外的試樣, -(1)組從焊 縫金屬處取,一(一)組從熔合線+2 mm(0,08in)處取。
The corrosion test specimenshall include the external and internal surface and a cross sectional surface including the weld zones in full wall thickness.The test specimens shall have a dimension of full wall thickness by 25 mm(1,0 in)along the weld and 50 mm (2,0 in)across the weld.For products with great wall thickness,e.g.exceeding 25 mm (1,0 in),more than one(1)specimen can be taken to cover full thickness.In such a case,all specimens shall fulfil the specified criteria.
腐蝕試樣應包括內外表麵和橫截麵表麵,包括全壁厚的焊接區。試樣的全壁厚尺寸應沿焊縫為25 mm(1.0in),沿焊縫為50 mm(2.0 in)。對於壁厚較大的蜜桃视频APP入口,例如超過25毫米(1.0英寸)的蜜桃视频APP入口,可以取-(1)個以上的樣品來覆蓋整個厚度。在這種情況下,所有試樣應符合規定的標準。
