Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0056] Thirty example and 13 comparative example alloys were designed. Each alloy is smelted by the aforementioned two-step smelting method of adding alloy raw materials according to the requirements of the addition amount of alloy raw materials (see Table 1 below), and then a rectangular ingot is cast by a vertical semi-continuous casting method.

[0057] Wherein embodiment 1-20 adopts the mode of secondary solid solution to produce, and concrete technology is as follows:

[0058] Heat the ingot at 700-980°C for 1 hour to 12 hours before hot rolling, the hot rolling speed is 5m / min to 200m / min, the rolling reduction rate is controlled above 75%, and the final rolling temperature is above 500°C. On-line water cooling after rolling, face milling after hot rolling.

[0059] Then carry out the first cold rolling, and the total reduction rate of...

Abstract

The invention discloses a Ce and B-containing titanium bronze alloy strip, which is characterized in that the titanium bronze alloy strip comprises the following components in percentage by weight: 2.50-4.00 wt% of Ti, 0.003-0.2 wt% of Ce, 0.001-0.02 wt% of B, and the balance Cu and unavoidable impurities; and a number of spot-shaped inclusions with the size larger than or equal to 1.0 micrometerin microstructures of the titanium bronze alloy strip is less than 30 / 1000 micrometer<2>. The titanium bronze alloy strip has excellent bending performance, and the anisotropy of the strength, especially the yield strength of the titanium bronze alloy strip is small. The invention further relates to a preparation method of the titanium bronze alloy strip.

Description

technical field [0001] The invention belongs to the technical field of copper alloy materials, in particular to a titanium bronze alloy strip containing Ce and B. The titanium bronze alloy strip has excellent bending properties and its strength, especially the anisotropy of yield strength is small. The invention also relates to a preparation method of the titanium bronze alloy strip. Background technique [0002] In recent years, with the rapid development of miniaturization and multi-functionalization of products in consumer electronics and other connector-related industries, designers need to choose copper alloy materials with higher strength and better formability to manufacture the contacts, so as to To meet the design requirements of thinner, lighter and miniaturized end products. Although beryllium-copper alloy, as a representative of high-strength copper alloy, can meet the above performance requirements, the application of beryllium-copper alloy is limited due to t...
