An indentation hardness test system includes a frame having a movable turret, a movable stage for receiving a part, a camera, a display, a processor and a memory subsystem. The turret includes an objective lens of a microscope and an indenter and the movable stage is configured for receiving the part to be tested. The camera captures images of the part through the microscope, which can then be provided on the display. The processor is coupled to the turret, the movable stage, the camera and the display, as well as the memory subsystem. The memory subsystem stores executable code that instructs the processor to capture and store a series of real-time images of the part using the camera, store associated stage coordinates provided by the stage for the images and display a composite image, which includes the series of real-time images assembled according to the associated stage coordinates, of the part.

An indentation hardness test system, comprising: a frame including an attached movable turret, wherein the turret includes a first objective lens that forms a portion of a microscope and an indenter; a movable stage for receiving a part attached to the frame; a camera for capturing images of the part through the microscope; a display; a processor electrically coupled to at least a portion of the turret, the movable stage, the camera and the display; and a memory subsystem coupled to the processor, the memory subsystem storing code that when executed instructs the processor to perform the steps of: capturing and storing a series of real-time images of the part, wherein the real-time images are provided by the camera; storing associated stage coordinates for the real-time images, wherein the stage coordinates are provided by the stage; and displaying a composite image of the part, wherein the composite image includes the series of real-time images assembled according to the associated stage coordinates. 2. The system of claim 1, wherein the series of real-time images are stored at a lower resolution than the captured images. 3. The system of claim 1, wherein the code instructs the processor to perform the additional step of: displaying a background pattern in the composite image for portions of the part that have not been captured. 4. The system of claim 1, wherein the code instructs the processor to perform the additional step of: normalizing the series of real-time images when at least one of the real-time images was captured by a second objective lens with a different focal length than the first objective lens before displaying the composite image of the part. 5. The system of claim 1, wherein the code instructs the processor to perform the additional step of: displaying an outline of the part in the composite image. 6. The system of claim 5, wherein the step of displaying an outline of the part in the composite image includes the steps of: examining a frame of an image stream of the part to locate an edge of the part; and moving the part in a direction parallel to the edge of the part such that the edge remains in the field of view for a next frame until the outline of the part is complete. 7. The system of claim 1, wherein the code instructs the processor to perform the additional steps of: overlaying a current position image of the part in the composite image; and indicating a location of the current position image. 8. The system of claim 1, wherein the code instructs the processor to perform the additional steps of: overlaying an indent position diagram on the composite image; and displaying a proposed indent location with an indentation outline that represents a geometry and size based upon an expected indenter, an expected orientation of the indenter, an expected indenter load and an expected hardness of the part. 9. An indentation hardness test system, comprising: a frame including an attached movable turret, wherein the turret includes a first objective lens that forms a portion of a microscope and an indenter; a movable stage for receiving a part attached to the frame; a camera for capturing images of the part through the microscope; a display; a processor electrically coupled to at least a portion of the turret, the movable stage, the camera and the display; and a memory subsystem coupled to the processor, the memory subsystem storing code that when executed instructs the processor to perform the steps of: capturing and storing a series of real-time images of the part, wherein the real-time images are provided by the camera; storing associated stage coordinates for the real-time images, wherein the stage coordinates are provided by the stage; and displaying a composite image of the part, wherein the composite image includes the series of real-time images assembled according to the associated stage coordinates, and wherein the composite image includes a background pattern for portions of the part that have not been captured. 10. The system of claim 9, wherein the series of real-time images are stored at a lower resolution than the captured images. 11. The system of claim 9, wherein the code instructs the processor to perform the additional step of: normalizing the series of real-time images when at least one of the real-time images was captured by a second objective lens with a different focal length than the first objective lens before displaying the composite image of the part. 12. The system of claim 9, wherein the code instructs the processor to perform the additional step of: displaying an outline of the part in the composite image. 13. The system of claim 12, wherein the step of displaying an outline of the part in the composite image includes the steps of: examining a frame of an image stream of the part to locate an edge of the part; and moving the part in a direction parallel to the edge of the part such that the edge remains in the field of view for a next frame until the outline of the part is complete. 14.
