Embodiment 1

[0034] Example one, yes Figure 3 (magnified 100x) for grain size rating.

[0035] An operating method for determining the average grain size of a metal, including the following steps:

[0036] Step S1: Make an electronic version of the three-circle grid;

[0037] Step S2: Insert the grain size picture into the document where the three-circle grid picture is located and make adjustments;

[0038] Step S3: Use the left mouse button to click on the three-circle picture to move above the grain size picture so that the two coincide;

[0039] Step S4: By counting the number of grain boundaries and the number of intercept points of the electronic version of the three-circle grid, in this process, the grain size picture is used as a field of view, and the three-circle picture is placed on the upper level of the corresponding field of view, so that five times, a total of five fields of view, and then the nodes of each field of view are counted, and the values are obtained: 136, 144, 127, 1...

Embodiment 2

[0047] Example two, yes Figure 4 (magnified 200x) for grain size rating.

[0048] An operating method for determining the average grain size of a metal, including the following steps:

[0049] Step S1: Make an electronic version of the three-circle grid;

[0050] Step S2: Insert the grain size picture into the document where the three-circle grid picture is located and make adjustments;

[0051] Step S3: Use the left mouse button to click on the three-circle picture to move above the grain size picture so that the two coincide;

[0052] Step S4: By counting the number of intercept points between the grain boundary and the electronic version of the three-circle grid, in this process, the grain size picture is used as a field of view, and the three-circle picture is placed on the upper level of the corresponding field of view, so five times, a total of five fields of view, and then the nodes of each field of view are counted, and the values are obtained: 109, 116, 114, 110, 95.

[0061] Example three, yes Figure 5 (magnified 100x) for grain size rating.

[0062] An operating method for determining the average grain size of a metal, including the following steps:

[0063] Step S1: Make an electronic version of the three-circle grid;

[0064] Step S2: Insert the grain size picture into the document where the three-circle grid picture is located and make adjustments;

[0065] Step S3: Use the left mouse button to click on the three-circle picture to move above the grain size picture so that the two coincide;

[0066] Step S4: By counting the number of intercept points between the grain boundary and the electronic version of the three-circle grid, in this process, the grain size picture is used as a field of view, and the three-circle picture is placed on the upper level of the corresponding field of view, so five times, a total of five fields of view, and then the nodes of each field of view are counted, and the values are obtained: 82, 83, 88, 80, 88.

Abstract

The invention relates to the technical field of metal average grain size calculation, in particular to an operation method for measuring metal average grain size, which comprises the following steps: step S1, manufacturing an electronic edition three-circle grid; s2, the grain size picture is inserted into a document where the three-circle grid picture is located, and adjustment is carried out; s3, the three-circle picture is clicked by a left key of a mouse to move to the position above the grain size picture, so that the two pictures are overlapped; and S4, counting the number of intersections of the grain boundary and the electronic edition three-circle grid. By manufacturing and using the electronic edition three-circle grid, an existing method for drawing the three-circle grid through compasses is replaced, the standard requirement is met, and the measurement precision is guaranteed; the method also has the advantages of being simple and convenient to operate and capable of being used for daily production inspection and proficiency verification and measurement auditing of laboratory approved items.

Description

Technical field [0001] The present invention relates to the field of metal average grain size calculation techniques, in particular to a method of operation for determining the average grain size of metals. Background [0002] The methods for determining the average grain size of metals include comparison method, area method and intercept point method. Among them, the intercept method has a straight line intercept method and a circular intercept point method. The advantage of the circular intercept point method is that it can automatically compensate for the error caused by deviation from the isometric crystal without too much additional field of view, and overcome the problem that the intercept method at the end of the test line segment is not obvious, so the circular intercept point method is more appropriate as a method of quality detection to evaluate the grain size, and the standard recommends the preferential use of three-circle mesh. At present, the use of three-circle gr...
