Description

用于制造超高强度涂覆或未涂覆钢板的方法和获得的板
本发明涉及制造具有改进的拉伸强度和改进的总延伸率的涂覆或未涂覆高强度钢板以及通过此方法获得的板。
为了制造各种设备，例如机动车辆的车身结构构件和车身面板的部件，现在通常使用由DP(双相)钢多相、复相或马氏体钢制成的裸露的电镀锌、镀锌或镀锌层扩散退火处理的板。
例如，高强度多相可包含具有/不具有一些残留奥氏体的贝氏体-马氏体组织，并且包含约0.2％的C，约2％的Mn，约1.5％的Si，这将导致约750MPa的屈服强度，约980MPa的拉伸强度，约10％的总延伸率。这些板在连续退火线上通过从高于Ac3转变点的退火温度淬火至Ms转变点以上的过时效温度并将板保持在此温度下给定时间来制造。任选地对板进行镀锌或镀锌层扩散退火处理。
鉴于全球环境保护，为了减轻汽车部件的重量以提高其燃料效率，期望具有改进的强度-延展性平衡的板。但是这样的板还必须具有良好的可成形性。
在这方面，提出了使用所谓的淬火和配分制造由钢制成的具有改进的机械特性和良好的可成形性的板。以拉伸强度TS为约1470MPa且总延伸率至少为19％的涂覆或未涂覆(裸露)板为目标。
因此，本发明的目的是提供这样的板及其制造方法。
为此，本发明涉及用于制造拉伸强度TS至少为1470MPa且总延伸率TE至少为19％的冷轧钢板的方法，所述方法包括以下顺序步骤：
-使由钢制成的冷轧钢板在退火温度AT下退火，以重量％计，所述钢的化学组成包含：
0.34％≤C≤0.40％
1.50％≤Mn≤2.30％
1.50％≤Si≤2.40％
0％<Cr≤0.5％
0％<Mo≤0.3％
0.01％≤Al≤0.08％
剩余部分为Fe和不可避免的杂质，退火温度AT等于或高于所述钢的Ac3转变点以获得退火钢板，
通过使退火钢板冷却至低于钢的Ms转变点的淬火温度QT(通常在150℃与250℃之间)来使退火钢板淬火以获得淬火钢板，以及
通过在350℃至450℃的配分温度PT下再加热淬火钢板并在15秒至150秒的配分时间Pt期间将钢板保持在此温度下来进行配分处理。
优选地，退火温度AT在870℃与930℃之间。
在两个实施方案中，在配分后，使钢板冷却至室温以获得未涂覆钢板：
在第一实施方案中，钢的组成使得0.36％≤C≤0.40％，Cr<0.05％且Mo<0.05％，淬火温度在190℃与210℃之间且配分时间Pt在90秒与110秒之间。
在第二实施方案中，钢的组成使得0.34％≤C≤0.37％，0.35％≤Cr≤0.45％且0.07％≤Mo≤0.20％，淬火温度在200℃与230℃之间且配分时间Pt在25秒与120秒之间。
优选地，随后对裸露的冷轧钢进行电镀锌。
在一个实施方案中，在配分后，对钢板进行镀锌，然后使其冷却至室温，以获得涂覆钢板，钢的组成使得0.34％≤C≤0.37％，0.35％≤Cr≤0.45％且0.07％≤Mo≤0.20％，淬火温度在200℃与230℃之间且配分时间Pt在25秒与55秒之间。
本发明还涉及由钢制成的涂覆或未涂覆钢板，以重量％计，所述钢的化学组成包含：
0.34％≤C≤0.40％
1.50％≤Mn≤2.30％
1.50％≤Si≤2.40％
0％<Cr≤0.5％
0％<Mo≤0.3％
0.01％≤Al≤0.08％
剩余部分为Fe和不可避免的杂质，组织包含至少60％的马氏体和12％至15％的残留奥氏体，拉伸强度至少为1470MPa且总延伸率至少为19％。
在一个具体实施方案中，钢板为未涂覆的，钢的组成使得0<Cr<0.05％且0<Mo<0.05％，并且屈服强度高于1150MPa。
在另一个实施方案中，钢板为未涂覆的，钢的组成使得0.35％<Cr<0.45％且0.07％<Mo<0.20％，并且屈服强度高于880MPa，拉伸强度高于1520MPa，且总延伸率至少为20％。
在另一个实施方案中，钢板为镀锌的，钢的组成使得0.35％≤Cr≤0.45％且0.07％≤Mo≤0.20％，拉伸强度高于1510MPa且总延伸率至少为20％。
现在将详细描述本发明，但不引入限制。
根据本发明，通过热处理由钢制成的热轧或优选冷轧的钢板来获得板，以重量％计，钢的化学组成包含：
-0.34％至0.40％的碳，以确保令人满意的强度和改进残留奥氏体的稳定性。这是获得足够的延伸率所必需的。如果碳含量太高，则热轧板太硬而不能冷轧并且可焊接性不足。
-1.50％至2.40％的硅以使奥氏体稳定，以提供固溶强化和延迟具有合适步骤的配分期间碳化物的形成，以防止在板的表面上形成对涂布性能不利的氧化硅。
-1.50％至2.30％的锰以具有足够的淬透性，以获得包含至少60％的马氏体的组织，大于1470MPa的拉伸强度和避免对延展性不利的偏析问题。
-0％至0.3％的钼和0％至0.5％的铬以提高淬透性和使残留奥氏体稳定，以便大大减少配分期间奥氏体分解。由于残留量，排除绝对零值。当钢板为未涂覆的时，可以排除钼和铬并且它们的含量可以各自保持小于0.05％。当通过镀锌涂覆钢板时，钼含量优选为0.07％至0.20％而铬含量优选为0.35％至0.45％。
-优选地，0.01％至0.08％的铝，其通常被添加到液态钢中用于脱氧目的。
剩余部分为铁和由炼钢造成的残余元素或不可避免的杂质。在这方面，Ni、Cu、V、Ti、B、S、P和N至少被认为是残余元素(其是不可避免的杂质)。因此，通常，它们的含量为Ni小于0.05％，Cu小于0.05％，V小于0.007％，B小于0.001％，S小于0.005％，P小于0.02％且N小于0.010％。添加微合金元素(例如0％至0.05％的Nb和/或0％至0.1％的Ti)可用于获得期望的显微组织和产品特性的最佳组合。
未经处理的钢板是根据本领域技术人员已知的方法制备的冷轧钢板。
在轧制之后，将板酸洗或清洗，然后进行热处理和任选地热浸涂覆。
当未涂覆板时优选在连续退火上进行的热处理和当涂覆钢板时优选在热浸涂覆线上进行的热处理包括以下顺序步骤：
-使冷轧板在等于或高于钢的Ac3转变点，并且优选高于Ac3+15℃(以获得具有完全奥氏体的钢板)但小于1000℃(以便不使奥氏体晶粒过于粗化)的退火温度AT下退火。通常，高于870℃的温度对于根据本发明的钢是足够的并且该温度不需要高于930℃。然后将钢板保持在此温度下(即保持在AT-5℃与AT+10℃之间)持续足以使钢中的温度均匀的时间。优选地，该时间大于30秒但不需要大于300秒。为了加热至退火温度，例如，将冷轧钢板首先以通常小于20℃/秒的速度加热到约600℃的温度，然后以通常小于10℃/秒的速度再次加热到约800℃的温度，并且最后以小于5℃/秒的加热速度加热至退火温度。在这种情况下，将板保持在退火温度下40秒至150秒的持续时间。
-通过使退火板以足够快以避免在冷却后形成铁素体并且优选大于35℃/秒的冷却速率冷却至低于Ms转变点的淬火温度QT(在150℃与250℃之间)来使退火板淬火，以获得具有由马氏体和奥氏体组成的组织的淬火板，然后最终组织包含至少60％的马氏体和12％至15％的奥氏体。如果钢包含小于0.05％的钼和小于0.05％的铬，则淬火温度优选在190℃与210℃之间。当必须对钢板进行镀锌时和当钢的化学组成使得0.34％≤C≤0.37％，0.35％≤Cr≤0.45％且0.07％≤Mo≤0.20％时，淬火温度优选在200℃与230℃之间。
-将淬火板再加热到350℃与450℃之间的配分温度PT。加热速度优选至少为30℃/秒。
-将板保持在配分温度PT下持续15秒至150秒的配分时间Pt。在配分步骤期间，将碳配分(即从马氏体扩散到奥氏体(因此富集碳)中)。
-任选地，如果不期望涂覆，则使板冷却至室温，或者如果期望涂覆，则将板加热至涂覆温度，对板进行热浸涂覆并冷却至室温。如本领域中已知的，热浸涂覆是例如镀锌，并且涂覆温度为约460℃。
加热至涂覆温度优选以至少30℃/秒的加热速度进行并且涂覆需要2秒至10秒。
无论是否施加涂覆，到室温的冷却速度优选为3℃/秒至20℃/秒。
当板未被涂覆且钢优选包含小于0.05％的铬和小于0.05％的钼时，配分时间优选为90秒至110秒。通过这样的处理，可以获得屈服强度大于1150MPa，拉伸强度大于1470MPa且总延伸率大于19％的板。
当板未被涂覆且钢包含0.35％至0.45％的铬和0.07％至0.20％的钼时，配分时间优选为15秒至120秒。通过这样的处理，可以获得屈服强度大于880MPa，拉伸强度大于1520MPa且总延伸率大于20％的板。
当板被涂覆时，钢优选包含0.35％至0.45％的铬和0.07％至0.20％的钼，并且配分时间Pt优选为25秒至55秒。在这些条件下，甚至可以获得拉伸强度高于1510MPa且总延伸率至少为20％的涂覆钢板。
作为一些实施例和比较，制造由钢制成的板，按重量计钢的组成和特征温度(例如Ac3和Ms)列于表I中。
将板冷轧、退火、淬火、配分并冷却至室温或者在配分之后且在冷却至室温之前镀锌。
在相对于轧制方向的横向方向上测量机械特性。如本领域中公知的，对于这样的高强度钢，在轧制方向上的延展性水平略好于在横向方向上的延展性水平。测量的特性是根据标准ISO16630:2009测量的扩孔率HER、屈服强度YS、拉伸应力TS、均匀延伸率UE和总延伸率TE。
未涂覆板的处理条件和机械特性列于表II中而涂覆板的处理条件和机械特性列于表III中。
在这些表中，AT是退火温度，QT是淬火温度，PT是配分温度。在表II中，GI是镀锌的温度。
表I
表II
表III
实施例1至14表明，只有用既不含铬也不含钼的钢S181和包含铬和钼两者的钢S80才能达到期望的性能，即，TS≥1470MPa且TE≥19％。在合金S181中，对于200℃的淬火温度QT和100秒的配分时间实现了期望的性能。在这种情况下，屈服强度高于1150MPa。
在包含铬和钼的合金S80中，对于220℃的淬火温度QT和30秒至100秒的配分时间(实施例7至10)达到了期望的性能。在这种情况下，拉伸强度高于1520MPa且总延伸率大于20％。此外，值得注意的是，所有包含Cr和Mo的实施例(7至14)具有显著低于实施例1至6(涉及不含Cr和Mo的钢)的屈服强度。
实施例15至33表明，当对板进行镀锌时(实施例27和28)，仅对应于包含Cr和Mo的钢的实施例能够达到期望的性能。对于钢S80，淬火温度必须为220℃，且10秒的配分太短而100秒的配分时间太长。当钢不含Cr且不含Mo时，拉伸强度总是保持低于1470MPa。
